Question

我正在尝试查找ejb。 server是wildfly 10，jdk 8，以下是代码片段

         InitialContext initialContext = null;
         Properties properties = new Properties();
         properties.put("java.naming.factory.initial",
                    "org.jnp.interfaces.NamingContextFactory");
         properties.put("java.naming.factory.url.pkgs",
                    "org.jboss.naming:org.jnp.interfaces");
         properties.put("jboss.naming.client.ejb.context",
                    "true");
         properties.put("java.naming.provider.url","http-remoting://localhost:9080");
        initialContext = new InitialContext(properties);
        initialContext.lookup("ejb:earname/jarname/bean!fullyqualifiedname");

我正处于异常

之下

我有主持人

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

在startup.sh文件中的

我为preferIPv4Stack

配置了JAVA_OPTS

JAVA_OPTS =“ - Djava.net.preferIPv4Stack = true”

我的服务器已启动并运行，在java.naming.provider.url的属性中，我每次遇到同样的问题时都尝试将url更改为localhost:9080/http:localhost:9080/jnp:localhost:9080。如何解决上述问题。

java.net.UnknownHostException：http-remoting：// localhost on lookup
